The invention belongs to the technical field of wireless power transmission, and relates to an LCC-S type wireless power transmission system and a parameter design method. The system comprises a full-bridge inverter circuit, a transmitting end LCC type resonance compensation network, a coupling coil mechanism, a receiving end S type resonance compensation network and an equivalent load module. The method comprises the steps of S1, carrying out initial parameter calculation and selection on the wireless power transmission system according to input, output and output characteristic curves; S2, obtaining a parameter optimization design constraint 1 according to the circuit output characteristics of the LCC-S type resonance topology in the detuning state; S3, obtaining a parameter optimization design constraint 2 according to the soft switching action implementation condition of the full-bridge inverter circuit power device; and S4, completing calculation and selection of system optimization parameters.
